SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 536,454, dated March. 26, 1895.

Application filed December 26,1894. Serial No. 532,9Il- (No model.)

To aZZ whom it rtrty concern:

Be it known that I, CLAUDIUS V. BOUGHTON, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Seal-Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings,

and to figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in seal-locks for railway cars, its object being to provide a lock the engaging members of which are sealed by a projection upon a tag which projection must be broken away from the tag, before the members of the lock can be disengaged to obtain access to the car.

To this end my invention consists of two engagingmembers which embrace the staple outside of the locking hasp one of such members being pivoted to the other, its outer or free end being adapted for revolving engage- 'ment with a projecting arm upon the other member, means concealed within the joint for preventing a reverse movement of the revolving member at the point of engagement with the projecting arm of the other member, a recess in the revoluble hub of the pivoted member adapted for the locking reception of the projection upon the tag and a slot in the hub of the other member, through which the projection'upon the tag is passed into engagement with the recess. 1

My invention further consists of other details of construction all of which will be more fully hereinafter described and claimed.

In the drawings, Figure 1 is a side elevation of my improved seal lock showing the engaging members in locked position. Fig. 2 is another elevation of Fig. 1 showing the revolving member out of engagement and in position for the insertion of the projection upon the tag. Fig. 3 is a detached inner face View of the member with the projecting arm. Fig. 4 is an under side view of Fig. 2 with the tag removed. Fig. 5 is a similar view of Fig. 1. Fig. 6 is a transverse section of Fig. 3 taken in the line 00-90. Fig. 7 is a similar section of Fig. 3 taken in the line y-y. Fig. 8 is a de- "projection.

Referring to the drawings it will be seen that my improved seal lock consists of two principal members 1 and 2. The part 1 is provided at its lower end with the hub 3 and at its upper end with the curved downwardly projecting arm 4, and 5 is aloop by means of which the member 1 is permanently secured 55 by a chain to the car. The member 2 is provided with the hub 6 which is loosely pivoted to the hub 3 by the axle 7 which passes through the central orifices 8 and 9 in the hubs 3 and 6. The lower end of the projecting arm 4 is provided with the T shaped slot 10, see Fig. 1,

adapted for the loose reception of the T deepest portion being at its upper end forming an abrupt shoulder 16.

The inner end of the hub 6 upon the pivoted member 2 is provided with the outside annular shoulder 17 adapted to register with the annular wall 12 upon the hub 3. Just within this annular shoulder 17 and concentric therewith is the annular groove 18in 0 which the projection 14 upon the inner face of thehub 3, rides. To the left of the orifice 9 in the hub 6 (see Figs. 8 and 9) is the spring pressed knob or spur 19 adapted to be pressed in or out of its recess 20 in the hub. This 5 knob 19 is adapted to engage with the shoulder 16 of the recess 15 in the hub 3 when the arm 2 is revolved in one direction and to pass by the same in the other direction. A wide recess 21 is cut in the inner face of the hub 6 2 figuration having centrally arranged upon its upon its upper edge the projection 23 provided with the narrow neck 24 and the engaging shoulder 25 adjacent to the neck 24. Q

My improved seal look just described is adjusted in position as follows: The pivoted member 2 is swung out of engagement with the arm 4 upon the member 1 and such arm is passed down through the staple upon the car in front of the hasp which is in engagement with the staple. The pivoted member 2 is then swung back to the position shown in Figs. 2 and 4 in which position the recess 21 in the revoluble hub 6 registers with the slot 13 in the hub 3. The projection 23 upon the tag 22 is then inserted through slot 13 into the recess 21. On swinging the pivoted member 2 into engagement with the arm 4 of the member 1 as shown in Figs. 1 and 5, the projection 23 upon the tag 22 is carried along until the shoulder 25 upon the projection 23 engages behind the wall 12. At this point the spring-pressed knob 19 in the hub 6 springs into the recess 15 in the hub 3, the shoulder 16 of which prevents a retrograde movement of the pivoted member 2. In this manner the two members are securely locked in their positions around the staple and the tag cannot be withdrawn entirely owing to the engagement of the shoulder 25 with the wall 12 of the hub 3. As the pivoted member 2 is swung into engagement with the arm 4 the inclined projection 14 upon the inner face of the hub 3 rides up upon the projection 23 on the tag adjacent to its narrow neck 24 and presses the same firmly against the floor of the recess 21 in the face of the opposite hub 6 which insures the breaking of the tag along the neck 24:.

The lock can be opened only by breaking off the projection 23 which permits the pivoted member 2 to be swung clear of the arm 4:. To remove the broken-off projection 23 the arm 2 is swung around its recess in the revoluble hub carrying with it the loose projection until such recess again registers with the slot 13, at which point the projection will fall out through such recess and the lock is again in position for the insertion of a fresh seal.

It will be seen that it is impossible to disengage the locked members without breaking the tag away from its suspending projection thus making it an absolute safe guard against any successful tampering with the same.

Upon the face of the tag are to be printed stamped or otherwise placed the name of the railroad and below it the station at which the car is sealed or the tags can be numbered consecutively, the tag when broken away being kept for reference if desired.

It will be noted that my improved seal-lock consists of but two principal parts both of which can be cast thus reducing the cost of manufacture to a minimum.

I claim 1. A seal-lock consisting of two engaging members which embrace the staple outside of the locking hasp, one of such members being pivoted to the other, its outer or'free end being adapted for revolving engagement with a projecting arm upon the other member, means concealed within the joint for preventing a reverse movement of the revolving member at the point of engagement with the projecting arm of the other member, a recess in the revoluble hub of the pivoted member adapted for the locking reception of the projection upon the tag and a slot in the hub of the other member through which the projection upon the tag is passed into engagement with the revoluble recess.

2. A seal-lock consisting of two engaging members which embrace the staple outside of the locking hasp, one of such members being pivoted to the other, itsouter or free end being adapted for revolving engagement with a projecting arm upon the other member, means concealed within the joint for preventing a reverse movementof the revolving member at the point of engagement with the projecting arm of the other member, a recess in the revoluble hub of the pivoted member adapted for the locking reception of the projection upon the tag a slot in the hub of the other member through which the projection upon the tag is passed into engagement with the revoluble recess and an inclined projection its highest point being nearest the slot in the wall for holding the projection on the tag, tight against the face of the pivoted member.

In testimony whereof I have signed my name to this specification in the presence of Witnesses:

W. T. MILLER, I. J. HARRIS.
